 | | Until Pepperberg began this research in the 1970s, few scientists had studied intelligence in parrots, and few do today Most inquiries have instead focused on monkeys, chimpanzees, gorillas, and dolphins, all of which are much more difficult to raise, feed, and handle. |
 | | Pepperberg especially likes parrots because, like humans, they're smart, long-lived (often up to 50 years), social animals that depend on communication for survival. |
 | | Pepperberg is careful to point out that such experiments have stimulated Alex and Griffin to master intellectual tasks both far different from--and possibly harder than--those they might achieve in the wild. |
